UNITED STATES ROSS H. IEORNEY, or DALLAS, TEXAS.

HIGH-PRESSURE GAS BURNER.

Application filed June 21, 1924.

To all whom it may concern:

Be it known that I, Ross H. FORNEY, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Higl1Pressure Gas Burners, of which the following is a specification.

This invention relates to burners for oil and gas and refers more particularly to an improvement in gas burners for stationary boilers or for marine use.

An object of this invention is to provide a gas burner. to be used in combination with mechanical atomizing burners in boilers of the type set forth and to provide a device of this character which will eliminate the necessity of separate oil and gas burners.

A further object is to provide a burner which will be simple in operation and construction.

A feature of the invention is that duplicat gas and oil burners may be eliminated.

Also in that by the use of this device, high efiiciency and satisfactory results may be obtained through the proper mixture of gas and air.

In brief, my invention is designed to furnish a high pressure burner which will be inexpensive, simple in operation and afford perfect efficiency in use, and with a view of eliminating expensive and complicated gas pressure reducing equipment which is used in practically all commercial burners of this character.

The present invention will be more read ily understood by reference to the accompanying drawings forming a part of this description, and which describes the invention fully and the application of various elements contained therein.

In the drawings:

Figure 1 represents a perspective view of the invention.

Figure 2 shows a detail view, partly in section, of the gas burner.

Figur 3 is a detail View of the means of attaching the invention to the boiler.

Figure 1 illustrates the method of applying the invention.

Similar characters of reference are used to indicate various novel features and elements of the invention throughout the different views, wherein: 1 denotes a tube or cylinder forming the body of the invention.

Serial No. 721,435.

This tube has a T member 3 screwed on one end thereof, and the other end of which is machined out at an angle, the purpose of which will be described more fully hereinafter. I

In the T member is screwed or otherwise suitably secured a plug at having a hexagonal head thereon. This plug is drilled and tapped to receive a rod 2, which is also threaded to engage the plug. Outside of the plug fl: a lock nut 5 is adapted to be se cured to lock the rod 2 in place after the rod has been adjusted in the plug.

A spider 6, attached to the rod, centers the latter in place. The tube 1 is machined or tooled out to allow free rotation of the spider.

A cone shaped member 7 is secured to the inner end of the rod 2 and has its sides tapered to effectually distribute the gas at the proper angle for intimate mixture with the entering air. A look nut 8 secures the cone in place on the rod at 2 The gas inlet is indicated by the numeral 3*.

The following description is simply for the purpose of clearly illustrating the method of attaching the invention and it will be understood that this is not claimed as a part thereof.

It will be observed by reference to Figure 8 that a tube 17 is slid within the rear plate of the boiler 11 and secured therein by set screw 30, passing through collar 18.

A casting 16 is screwed onto the tube 17 and has an extension 19, which latter has attached a yoke 25 with a head 23 and set screw 24:.

The following description now deals with my invention, with various references being made to adjacent mechanism to facilitate a perfect understanding of the improvement thereupon.

The tube 1 is adapted to slide into the tube 17 and has secured thereto a member 29, the purpose of which is to secure the tube 1 in place. Member 29 is provided with a set screw 27, which is adapted to secure this member to the member 21 and also permits of adjustment of the tube 1 in and out of tube 17. The lower end of the member 29 is suitably drilled to admit a plug 21. The latter member is secured in member 29 by means of lock nuts 22 on either side thereof.

One end of the member 21 is provided with an enlarged head or section 20 which engages the member 19, as shown in Figure 3.

It will be noted by reference to Figure 1, that the plug 21 is retained in position in the boiler by the use of yoke 25 which is provided with a set screw 2a tohold the same in position when swung into position illustrated in this figure.

The tube 17 and hose 15 attached to valve l0 and pipe 10 form part of the oil burning equipment not claimed as a part of this invention.

In the operation of this invention, gas is fed to the burner through the header 9, valve 14 and hose 16. The latter is secured to the valve 14* by a union, nipple and hose clamp 13 said valve being in turn secured to the header 9.

The opposite end of the hose is secured to the T member by means of a nipple and hose clamps 14. Gas pressure is regulated in the main 9 by means of a control valve (not shown).

The gas passes through the burner pipe 1, thence out through the opening provided between the end of the tube 1 and conical plug 7 illustrated clearly in Figure 2. It is obvious therefore that the result sought is obtained through the peculiar construction of this nozzle, the construction of which is brought out in Figures 2 and 4:.

Attached to the end of tube 1 is a conical shaped impeller 32. This impeller is situated in such a manner as to throw the entering air in a circular motion; the entrance through which the air passes is indicated by arrows, see Figure 4. This feature assists in the mixing of the gas and air.

Surrounding the inner end of the burner and the conical impeller 32 is an inverted bladed cone 33, see Figure 4E. The blades and cone throw the entering air into the gas stream in such a manner as to facilitate the intimate mixture of the said gas and air.

The burner is adjusted in and out of the furnace wall in order that the flame will just clear the inner edge of the opening in the brick wall 84. If the burner is pulled to the rear too far, the flame will impinge on the edge of the brick, and if the same is pushed forward too far, it will allow air to pass between the conical shaped gas flame and the inner edge of the brick work, thus preventing a proper mixture of the gas and air.

It should be understood that minor changes in the arrangement and construction of this invention may be made without departing from the spirit and meaning of the following claim.

I claim:

A high pressure gas burner of the char acter described including, in combination, an inverted bladed cone mounted in an opening in the wall of a furnace, an air supply communicating therewith, an end plate for said air supply opposite the cone, a conical shaped bladed cone, a tube slidably mounted through the end plate and carrying the conical shaped bladed cone so that the latter may be adjusted towards and from the inverted bladed cone, the inner end of the tube being also provided with a conical valve seat, a branch conductor associated with the outer end of the tube, a gas conducting pipe connected to the conductor for supplying gas to the outer end of the tube, a cone shaped valve mounted at the inner end of the tube for coacting with the cone shaped bladed cone and for controlling the supply of gas from the tube, and means for slidably mounting and operating the valve from a point exteriorly of the plate.

In testimony whereof I have signed my name to this specification.

ROSS H. FORNEY.
